It's finally here! My compilation of all the ponies with moustaches! I guess Twi went crazy with #25. I have each of them vectored individually if you want 'em, also, My original sketches of them are in my stash. Hooray for Reddit and EQD for posting me!

I was considering it, I was also considering giving her a mullet! but it just wouldn't look like her anymore. What I finally came to with each of them is what both fit their personality and fit their character design

actually I was originally gonna put "hulkamania" in AJ's shirt! As for the other likenesses... welp, they are each inspired by pretty much what you guessed but more stylistically than literally. I basically gave them some sort of accessory to the mustache I thought would either suit them best or just plain look funny. Perty amazing observation tho! You were spot on, but fluttershy is joe dirt inspired and Dashie is basically somewhere between me and Dan VS (which is a very small gap indeed)
